Tom Leppert, the mayor of Dallas (an officially nonpartisan position), is being mentioned as a possible Senate candidate in 2012.

It’s no secret that the mayor wants to run for Senate in 2012, and that his most loyal supporters are on board.
Running for re-election as mayor and then running for Senate could be impractical, since the GOP primary is only months after the next mayoral term would begin.
So Leppert, a Republican, has been waiting for Sen. Kay Bailey Hutchison, R-Dallas, to make a decision on her plans. Her third term ends in 2012, and she has not said whether she’ll seek re-election.
Leppert and Hutchison are allies, and he would rather not run against her in a March 2012 primary.

Leppert endorsed Rick Perry for governor earlier this year. In March, he appeared with Sarah Palin at a fundraising dinner for a new women’s pregnancy center in Dallas.
